136.975 MHz in 25 kHz increments (760 channels). The operation mode is Simplex, which is
transmitting or receiving only in turns.
NOTICE:
Before using the radio the first time charge the battery for at least 10 hours with 250 mA!
Battery Test
Press button "LAMP/ BATT. TEST"

…
4 LEDs ON
⇒
battery partially discharged, reduced operating time.
1 LED ON
⇒
battery discharged, charge the battery immediately.
NOTE : Do not discharge battery completely during radio operation (no indicator ON). Self-
discharge of battery when not in use (radio switched OFF) permitted.
Receive Operation
1. Connect antenna to the antenna socket
d
.
2. Rotate the VOL control
c
clockwise to turn the radio ON.
3. With the MHz-
i
and kHz-
j
selector switches set the desired operating frequency.
WARNING! MHz-switch stops at each band-edge (118 / 136)! Risk of destruction!
4. To check receiver switch OFF squelch circuit (toggle switch
f
towards OFF position
that is opposite " SQ "). On a free channel basic receiver noise with steady volume should
be audible.
5. Standard Receive Operation
Switch the Squelch-circuit ON (SQ-toggle switch
f
towards position " SQ "). Receiver noise, weak signals
and interference pulses are blocked. Adjust the
volume control
c
to a desired level.
6. To obtain full receiving radio range switch OFF the
squelch
f
. Now the radio is noisy during standby
operation but no weak signals are suppressed.
7. In noisy environment hold speaker close to your ear
or use noise canceling headphone for this purpose.

Transmit Operation
When using the helical antenna hold transceiver vertically, preferably with the left hand.
Care for an all-round obstacle free location; the called station
should be within line-of-sight distance.
Do not hold the radio such as the antenna gets very close to, or
touching, exposed parts of the body, especially the face, shoulder
or the eyes.
Please keep radio discipline. The channel must be clear before
transmitting.
Rotate the volume control
c
clockwise to turn ON the radio.
With the MHz-
i
and kHz-
j
switches set the desired operating
frequency.
Press and hold the push-to-talk button
g
. Speak loud, slow and
clear!
When the built-in microphone is used, speak into the microphone
l
from a distance of 3 to 5
cm. After your message release the PTT button
g
to clear the channel and hear the reply.
Charging the Battery
Plug DL-5A charger into accessory jack
h
. Connect charger to mains.
Observe charging temperature of 0°C
…
+40°C.
Normal charge: ca. 10 hours with up to 250 mA.
Transceiver not in use should be left connected to the charger. This keeps the battery fully
charged and allows maximum operating time.
Continuous charging via
h
of FSG 5 in operation or switched OFF is permitted.
Use only DITTEL chargers.
Always recap accessory jack
h
after charging.
Frequency Display Illumination
The frequency display may be illuminated by pressing the "LAMP/ BATT. TEST" button
e
,
independent whether the radio is switched ON or OFF.
Accessories
The accessory jack
h
allows connection of accessories for various applications and op-
erating conditions. When an external dynamic microphone of < 200 Ω DC impedance is
connected, the built-in microphone is automatically switched OFF. In noisy environment a
second loudspeaker or a noise canceling headphone with at least 30
Ω is recommended.
